Stories hitting the newspaper and this website on Sunday are the first in a three-day cycle of data digestion relevant to the university's statewide political survey gathering information on the U.S. Senate race in Massachusetts and the Presidential race.

On Sunday, we will take a look at where the U.S. Senate race between Republican Sen. Scott Brown and chief Democratic rival Elizabeth Warren stands.

On Monday, we will look at where the Republican Presidential candidates rank in the minds of Bay State voters and dig into President Barack Obama's job approval rating. The survey also includes specific match-up questions, placing Obama against potential Republican opponents, and we will look at which GOP candidate gives the president the most solid challenge.

On Tuesday, stories will reflect trait assessments of Brown and Warren, to paint a picture of where their respective messages are hitting or missing among the voters surveyed.

In the early morning hours of Sunday, Monday and Tuesday, the Western New England Polling Institute will release the associated data sets on its website and through its email media lists. Data will also be available in full on MassLive.com.

The partnership, which will bring unique and in-depth political coverage to the readers of The Republican, MassLive.com and El Pueblo Latino, is the latest effort by the Springfield-based news organization to deliver the most comprehensive election-year coverage in Massachusetts.
